摘要
This invention discloses a method of enriching raw oil shale by crushing and pulverizing raw oil shale or similar oil bearing materials into smaller, lean oil particles and larger, oil rich particles; floating the larger, oil rich particles in a heavy media organic liquid which causes the oil rich lighter particles to float on the surface and causes the heavier, mineral containing particles to sink. The floating larger, oil rich particles thus obtained contain increased percentages of oil bearing constituents.
